World Solve

Smart thermostats have improved efficiency, but many systems still require manual adjustment to truly optimize comfort without wasting energy throughout changing conditions. Fully automated, effective climate optimization remains an unresolved technical challenge.

Advanced prosthetics with sensory feedback exist but remain far too expensive for widespread use, especially in lower-income regions where basic prosthetics are already hard to access. Closing this affordability gap remains an unresolved global health technology challenge.

Advanced filtration technology exists, but cost and infrastructure requirements keep effective solutions out of reach for many communities facing the most severe water contamination issues. Solving this affordability and deployment challenge remains urgent.

Solar panel efficiency has improved significantly, but in regions with less sunlight or higher installation costs, achieving full cost competitiveness with traditional energy remains inconsistent. Closing this gap universally remains an unresolved technical and economic challenge.

Effective air purification technology exists but often remains too expensive for widespread use in low-income housing, where indoor air pollution can be a serious health concern. Making this technology genuinely affordable remains an unresolved public health challenge.

Telemedicine can expand healthcare access, but its usefulness is limited in areas where internet connectivity is too unreliable to support video consultations consistently. Solving this connectivity dependency remains an unresolved infrastructure challenge.

Solar lighting technology exists, but durability and cost issues have limited how widely and reliably it can be deployed in regions that need it most. Improving both affordability and long-term reliability remains an unresolved challenge.

Some compression methods shrink files perfectly for certain data but fail badly on others, and no universal, lossless method works equally well for everything. Solving this could make data storage and transmission dramatically more efficient.

Known as Goldbach's Conjecture, this simple-sounding statement has been checked for enormous numbers without exception, but never formally proven true for all numbers. It remains one of the oldest unsolved problems in mathematics.

Prime numbers appear to follow patterns at large scales but seem random up close, and mathematicians still lack a full explanation for this behavior. Understanding it better could improve encryption methods that rely on primes.

This century-old conjecture predicts a hidden pattern in how prime numbers are distributed, but nobody has ever proven it true. A proof would deepen our understanding of numbers in ways that ripple into cryptography and physics.

Free expression is valued almost everywhere, but so is protection from harassment, incitement, and harmful misinformation, and these values often conflict directly. No universal line exists for where one right ends and the other begins.

Some countries and individuals consume vastly more resources than others, and there's no broadly accepted definition of what a fair share would even look like. This makes global cooperation on resource use difficult to justify to everyone involved.

Advances in medicine keep pushing life expectancy higher, but there's no consensus on whether radically extending life is actually good for individuals or society. This question becomes more urgent as anti-aging research advances.

Factory farming, animal testing, and habitat destruction all cause animal suffering for human benefit, but there's no consistent ethical standard for how much suffering is acceptable and why. This gap shows up in inconsistent laws and practices worldwide.

Gene editing could prevent serious diseases, but it also opens the door to selecting traits that have nothing to do with health. Society hasn't agreed on where prevention ends and something more troubling begins.

Surveillance can prevent crime and terrorism, but it also erodes personal freedom, and there's no consensus on where the right balance lies. Different societies draw this line in very different places.

Many developing countries need roads, power, and water systems but often can only afford them by taking on debt that becomes difficult to repay. Finding a fairer way to fund this development remains unresolved.

International courts and diplomacy exist, but nations still frequently settle disputes through force when other methods fail or are ignored. A stronger, more trusted system for resolving conflicts peacefully remains unbuilt.

Personal and corporate data crosses borders constantly, but laws about who owns it and how it can be used vary wildly by country. This patchwork makes real data protection difficult to enforce globally.
